'Appiicauon fusa January e, 190s. v serial No. 470,408.

To all whom it may conce/var,

' Be it known that werioseph B. CARD and FRANK MQARDLE, citizens ol? the United States, residing at Chica-go, 'in the county of Cook and State of Illinois, have invented certuin new and useful In] proveniente in Apparatus for rlreeting Wooden Blocks, of

. which the following n specification, refertrent-ment of Wooden fed into seid tank et the top, discharged therefrom by' gravity through the bottoni und carried away without the necessity oi loading' such materiel upon cars or trucks, ov siniilur conveyances, running the same into the treating tenk and running them out utter the materiel is treated.l n

ln the"aecoi'npunying drnwingsf-it`1gnrc l is un elevation, purtly in section, showing the treating tank part-ly broken zuvey; und Fig. 2 is another elevation, viewed y't'roln the right in Fig. l, showing the treating tank partly broken away.

Referring` to the drevvings,-f3,indicates a treating tank, which is provided vvlth a. re-

ceiving opening l et its top adapted to be' closed. tightly'by e cover 5. The receiving tank 3 has n bottom 6 which is shapedllke an inverted trust-nm of noone and 1 s provided with suitable discharge openings 7 which are provided with covers 8 `which are preferably hinged and Yare adapted to be locked over the openings by n suitable iock 9 so as to be nir und liquid tight, as is also the onse with the cover 5. 10 indicates e pipe opening at the bottoni of the treetlng tenk 3, and Alla pipe leading from its top.

The pipes 1.0 und 11 are adapted to be connected with suitable'pmnps (not Shown and of any well known form and description) by mcansot which steam moy be blown through the tank, the. :tir may be exhausted therefrom and preservative fluid of any well-known kind intrmluced into the tank,

put into pressure therein and removed theref from when the treatment is over. As all these parts may be of any Well-known form and description and form in themselves no part of rny present invention, We'liave not illustrated and believe it is unnecessary to describe them more fully.

12 indicates n conveyer, which leads from any `suitable source of supply,` as, for i11-v stunce, a sawing-table 13 and conveyer 14,`

to a discharge spout 15 supported on suitable supports HS on the top of the tank and having its discharge end in registry with the opening 4 in the top of the tank. The function of this 'conveyer is to convey the material to be treated with preservative fluid, such, for instance, as pavin blocks und similar blocks, from any suit-ab e source ot supply, as from the seid sawing-table, tov

-the top of the treating tank end deliver them into the suine until the desired numberof such Wooden blocks are fed into the tank.

17 indicates a receiving frame, which is in which may`l the form of :1 box-like structure, be entirely open at. its sides above the discharge guides, as illustrated in theV drawings, so as to discharge the blocks upon the carrier hereinafter described. The frame is prfwidod with sides 18 which may be formedv ot any suitable material, as tened to uprights 19.

2() indicatesguide-bars. which are located by boards, fasin the bottoni ot.' the receiving frame 17 and I formed of iron bars, or any other suitable materia l, ure sloped so :1s to direct the blocks vfrom the treatlng discharged upon them tank it'or treatment toward the conveyors hereinafter described. Preferablys shown in the drawings, these guide-bers nre-highest in the middle upon nv line extending the' Vlength of the receiving frame ut richt angles to said bars and sloping downward and outyvord upon both sides of said central line extending to the open sides of the receiving frame. 4 2l indicates conveyers consisting of sprockebchnins 22 and conveying members 23 carried by said sprocket-chains. Wit-h the guide-bars 20 forlned in the shape above described, these conveyors are, two 1n numi ber, located one upon euch open side of the machine. The conveyers 21 carried by] guide-Wheels 2li-25 and a sprocket-Wheel' 26 which nre driven in any Well-known and approved manner extend .horizontally the length of the'scries ot' guidedml's 2() andlj l then extending iipwaitl and onlwiiril to tht.`

A siiitahle l'ii'eservative li'iiid is then let into the tank until the tank filled above the level of the contained blocks and the said Huid is put iincler pre.' .sure in sait] tank in any Suitahle inai'ii'iet' until the hlofl have heeon'ie ii'i'ipregna'ted with the preserving liqnitl. The preerving -lirpiifl is then rlrawn olf' from the tank.
